Hmmm.
LIFE after death has been “confirmed” by scientists who have discovered consciousness continues even once a person has died.

A new cheaper way in creating magnets.
US researchers have created a powerful permanent magnet out of iron and nitrogen, two plentiful cheap materials, as part of a programme to cut the need for ‘rare earth’ metals.
It is only a tiny sample, a film 500nm thick, but it is the real thing.
“To the best of our knowledge, this could be the first experimental evidence of the existence of a giant saturation magnetisation, an obviously large coercivity, with a magnetic energy product of up to 20 MGOe, in a bulk-type FeN sample.” said the team in ‘Synthesis of Fe16 N2 compound free-standing foils with 20MGOe magnetic energy product by nitrogen ion-implantation’, a Nature Scientic Reports paper written by a team from the University of Minnesota, Los Alamos National Laboratory and Oak Ridge National Laboratory.
Math isn’t everyone’s strong suit, especially those who haven’t stretched that part of their brain since college. Thanks to the wonders of image recognition technology, we now have Mathpix, an iOS app that lets you point your phone camera at a problem and calculates solutions in seconds.
The interface looks like any standard camera app: simply drag the on-screen reticle over the equation and the app solves it and provides graph answers where appropriate. More useful is a step-by-step guide offering multiple methods to reach a solution, making this a bona fide educational tool. It uses image recognition to process problems and pings its servers to do the mathematical heavy lifting, so it likely requires an internet connection to work.
Mathpix was envisioned by Stanford PhD student Nico Jimenez, who was advised by Stanford grad Paul Ferrell. The app’s other developers are high schoolers Michael Lee and August Trollback, which is impressive for an app that claims to be the first to visually recognize and solve handwritten math problems.

New spin on all things that are Singular. Hmmm — so if Singularity becomes a religion; is Ray Kurzweil its God?
A colleague forwarded John Horgan’s recent Scientific American article, “The Singularity and the Neural Code.” Horgan argues that the intelligence augmentation and mind uploading that would lead to a technological singularity depend upon cracking the neural code. The problem is that we don’t understand our neural code, the software or algorithms that transform neurophysiology into the stuff of minds like perceptions, memories, and meanings. In other words, we know very little about how brains make minds.

Another exampme of how precision works.
While pregnant with her first child, Rhea Birusingh started experiencing blurry vision that her OB-GYN dismissed as an expected pregnancy-related change, but three months later, she went to her ophthalmologist, who discovered an inoperable 2-centimeter benign brain tumor behind her right eye. Now, nearly four months later, Birusingh’s son is healthy and her vision is normal, thanks to a powerful, precise radiation treatment.
“When you’re a pathologist and your eyes are a money maker, you start to get a little bit worried,” Birusingh, 37, of Howey-in-the-Hills, Florida, told FoxNews.com.
Doctors at UF Health Cancer Center – Orlando Health decided to use the treatment, called proton beam therapy, because Birusingh’s tumor was adjacent to her hippocampus, which is critical for short- and long-term memory and learning. Proton beam therapy works differently from conventional radiation treatments, which rely on X-rays. Birusingh was the first patient to undergo the treatment— which uses a three-story, 200,000 pound machine— at the hospital.
Very promising. Wonder how effective it is with Prescription Med. Addictions.
A type of brain cell known as microglia plays a key role in reducing the effects of cocaine in the brain, according to a major study by a team from the Research Institute of the McGill University Health Centre (RI-MUHC) in Montreal.
The discovery, published in the journal Neuron, establishes for the first time that microglia can diminish the adverse changes to neural circuitry brought on by the chronic use of cocaine and has significant implications for developing an effective treatment for addiction.
Microglia may not be as well known as neurons, the brain cells that relay messages, but they have many important functions. They constantly monitor their environment, and can act to maintain normal brain functioning. When they find something amiss, they can produce molecules that instruct neurons to make adaptive changes to their connections. One such example is the inflammatory molecule known as tumor necrosis factor (TNF).
